Mechanism of geopolymerization and factors influencing its development: a review
Divya Khale,Rubina Chaudhary +1 more
TL;DR: In this paper, the authors present the work carried out on the chemical reaction, the source materials, and the factor affecting geopolymerization, and demonstrate that certain mix compositions and reaction conditions such as Al2O3/SiO2, alkali concentration, curing temperature with curing time, water/solid ratio and pH significantly influences the formation and properties of a geopolymers.

Geopolymers and Related Alkali-Activated Materials
John L. Provis,Susan A. Bernal +1 more
TL;DR: In this paper, the synthesis of alkali-activated binders from blast furnace slag, calcined clay (metakaolin), and fly ash is discussed, including analysis of the chemical reaction mechanisms and binder phase assemblages that control the early-age and hardened properties of these materials.

Geopolymers : inorganic polymeric new materials
TL;DR: In the last few years, technological progress has been made in the development of new materials such as "geopolymers" and new techniques, such as ''sol-gel'' as mentioned in this paper, opening up new applications and procedures and transforming ideas that have been taken for granted in inorganic chemistry.

The geopolymerisation of alumino-silicate minerals
Hua Xu,J.S.J. van Deventer +1 more
TL;DR: In this paper, the effect of mineral properties on the compressive strength of the synthesized geopolymer was investigated, and it was shown that a wide range of natural Al-Si minerals could serve as potential source materials for the synthesis of geopolymers.
Journal ArticleDOI
The nature of C-S-H in hardened cements
TL;DR: In this paper, the morphology, composition, and nanostructure of C-S-H in a range of hardened cements were investigated. But the authors focused on the inner product (Ip) of a slag-based mixture of Portland cement and slag.
